Frequently asked questions
How do I merge multiple Excel files online into one workbook?
Select "Merge", add two or more Excel files, and download the combined workbook. Every source sheet remains a separate sheet. When sheet names repeat, the tool adds a number to keep each name unique. Processing stays in your browser.
Does this tool support .xls files (older Excel format)?
Yes. You can select .xlsx or older .xls files. The merged workbook and split files are downloaded in .xlsx format.
Are my Excel files uploaded to any server?
No. All file processing is performed locally in your browser using JavaScript. Your spreadsheet data never leaves your device and is not sent to UsefulGo servers.
Will the merged file preserve formulas and formatting?
Cell values, formatting, and basic formulas are preserved. Complex features like cross-workbook formula references, macros (VBA), and pivot tables may not transfer correctly.
